Special guests singing the classic baseball song during the seventh-inning stretch has become a tradition at Wrigley Field.

Although, not all of them go as smoothly as it did for the radio hosts.

There’s not much that needs to be said about Ozzy Osbourne.

Mike Ditka was late for his performance, almost causing a riot amongst the Cubs faithful.

Can it really be considered Mr. T if he doesn’t call anybody a fool?

Scottie Pippen forgot the lyrics two lines into the song.

Bickley kept his opening monologue short, as the headliners weren’t able to get any bands or artists to be their opening act.

“What’s up Chicago homies,” Bickley said. “I apologize for what you’re about to experience.”

Marotta started the count to three to start the song, but Bickley corrected him by adding the “a” in front of each number, making it “a-one, a-two, a-three,” like they do in Chicago.

Marotta also went with what has become a trademark move for most Cubs seventh inning stretch singers: swinging his arm with the microphone pointed toward the stands so that the crowd could take it away.

During the famous “root, root, root for the Cubbies” part, Bickley actually says “Cubbies” while Marotta doesn’t, letting the crowd finish the lyric and perhaps keeping his allegiance to the hometown D-backs.

The song actually received thunderous applause from the Sloan Park crowd.

“What a joke,” Bickley jokingly said as the modern-day Simon & Garfunkel left the stage.

And although the performance may merit a chance at the real thing at Wrigley Field in Chicago, the musicians are returning to their day jobs, leaving us all wondering what could have been.
